C207 Connector
Did a search, couldn't find what I was needing.
Does anyone happen to have the pinouts for the C207 on an '87 GTA L98 car?
Trying to trace down the FI wires but can't find them

Of course, I'm referring to the FI power wires, not the ones going to the ECM. Hopefully someone will have this.

If by FI, you are referring to the fuel injectors. The wiring is as follows..
Bank One (injectors 1,3,5,7) is a pink/black wire going to pin "D" of connector C221 and then to the INJ1 fuse in the fuse panel.
Bank Two (injectors 2,4,6,8) is also a pink/black wire going to pin "A" of connector C221 and then to the INJ2 fuse in the fuse panel.
They do not go through connector C207 at all for the power to them.
The wires for the injectors going to the ECM are a light blue wire for Bank One and it goes to pin "D15" of the ECM
Bank Two is a light green wire and goes to pin "D16" of the ECM.
None of the wires for the injectors go through connector C207 on your car.
BTW and before you ask, connector C221 is a six pin connector behind the right hand side of the instrument panel near the ECM.
